REPORT: Apple Will Have Incredibly Fast WiFi In Its 2013 Mac Computers

The new WiFi chips aren't finished yet, but they are capable of speeds as high as 1.3Gbps, which is commonly referred to as "Gigabit WiFi."

This won't necessarily make your Internet speeds faster, but it is good for wireless technologies like AirPlay and swapping files between computers in your home.

Here's the technical explanation of the new WiFi chips from TNW:

802.11ac is often referred to as 5G WiFi , offering faster throughput, higher capacity, wider coverage and improved power efficiency. Products offering 802.11n connectivity (found in most consumer electronics) provide connections up to 450Mbps with three antennas, while 802.11ac equivalents start at 450Mbps for one antennae and are capable of almost tripling its predecessor with 1.3Gbps throughput via three antennas.
